Asset Tracker v2 - How to monitor the On/Off state of the sliding switches: sw1 and sw2 reported every minute from the nRF9160DK device to a topic of the AWS IoT Core?

[Jacek Majda]

I have built and run the application: Asset Tracker v2 using Segger IDE with nRF Connect SDK 1.8.0 , and my nRF9160DK device communicates with the  AWS IoT Core topics.

I can see the battery voltage data (with its time stamp) reported every minute from my nRF9160DK device to the shadow topics of the AWS IoT Core and I can also see the button-pressed data reported (when a button is pressed) from my nRF9160DK device to the AWS IoT Core topic: <IMEI>/messages.

As a next step, I would like to see the On/Off state of the sliding switches: sw1 and sw2 reported every minute from my nRF9160DK device to a topic on the AWS IoT Core.

How can this be done?

Hi,

I did not touch this setting and it is still set in the overlay-aws.conf file as follows: CONFIG_AWS_IOT_MQTT_PAYLOAD_BUFFER_LEN = 2048

As requested, I attach a raw modem trace file that I created today using Trace Collector v2.

JM

Hi,

 

Thank you for the trace. The packet that aws sends to you is a bit larger than 2048. Can you try setting the CONFIG_AWS_IOT_MQTT_PAYLOAD_BUFFER_LEN=2304 and see if this helps the scenario?

 

Kind regards,
